Proposed is an adaptive multipath control technique to suppress interference radiation from a transmitter to the non-target receivers for broadband private wireless access systems. In the proposed scheme, deep and wide null creation techniques are employed in the adaptive array antenna to effectively use a limited number of antenna degrees of freedom under rich scattering indoor channel conditions. Computer simulation confirms that the proposed scheme is very effective in control of the transmit antenna directivity to suppress interference radiation, thereby the interference to the non-target receivers is largely reduced, and BER performance is greatly improved with low outage probability.
